New Zealand Data Sheet NEW ZEALAND DATA SHEET EPIPEN® 1. Product Name EpiPen® 300 µg Adrenaline (epinephrine*) Auto-Injector * in some countries, adrenaline is known as epinephrine 2. Qualitative and Quantitative Composition Each auto-injector delivers a single 300 microgram (µg) intramuscular dose of adrenaline (epinephrine) from Adrenaline Injection 1:1,000 USP (0.3 mL). Excipient(s) with known effect EpiPen® contains sulfites. For the full list of excipients, see section 6.1. The EpiPen® device provides adrenaline (epinephrine) for intramuscular auto-injection in a clear, colourless, sterile solution prepared from adrenaline with the aid of hydrochloric acid in Pyrogen Free Water. The EpiPen® Auto-Injector contains 2 mL Adrenaline Injection 1:1,000 USP and is designed to deliver a single 0.3 mL dose of 300 µg. Each 0.3 mL dose contains: Active; 300 µg adrenaline, Inactive; 1.8 mg sodium chloride, 0.5 mg sodium metabisulfite and hydrochloric acid to adjust pH. The pH range is 2.2-5.0. 3. Pharmaceutical Form Solution for injection in an auto-injector (prefilled, disposable automatic injection device) for intramuscular use. The injection is a clear, colourless solution. 4. Clinical Particulars 4.1 Therapeutic indications For the emergency treatment of anaphylaxis (acute severe allergic reactions) due to insect stings or bites, foods, drugs or other allergens. 4.2 Dose and method of administration Dose Selection of the appropriate dosage strength is determined according to patient body weight and this decision should be based on careful assessment of the individual patient and recognition of the life-threatening nature of reactions for which EpiPen® is prescribed. Adults ( 30 kg): Intramuscular injection of EpiPen® Auto-Injector containing 0.3 mg adrenaline injection (0.3 mL, 1:1000). Page 1 of 11 Children (15 to 30 kg): Intramuscular injection of Epipen Jr®. Auto-Injector containing 0.15 mg adrenaline injection (0.3 mL, 1:2000). The doctor or pharmacist may choose to recommend more or less than this amount*. With severe persistent anaphylaxis, repeat injections with an additional EpiPen® Auto-Injector may be necessary. To manage severe anaphylaxis, repeat EpiPen® injections may be necessary. Each EpiPen® Auto- Injector is used once only. The EpiPen® dose may be repeated every 5 to 15 minutes if symptoms recur or have not subsided (see section 4.9). Method of administration 1. Before using, check to make sure the solution in the Auto-Injector is not brown in colour. If it is discoloured or contains a precipitate, do not use, since these changes indicate that the effectiveness of the drug product may be decreased. 2. The delivered dose of the EpiPen® Auto-Injector should be injected intramuscularly into the anterolateral aspect of the thigh, through clothing if necessary. The EpiPen® Auto-Injector should be pushed firmly into the outer mid-thigh until a “click” is heard or felt and it should then be held firmly against the thigh for approximately 3 seconds to ensure the dose is delivered. Instruct caregivers of young children who are prescribed an EpiPen® and who may be uncooperative and kick or move during an injection to hold the leg firmly in place and limit movement prior to and during an injection. 3. DO NOT INJECT INTRAVENOUSLY. Every effort should be made to avoid inadvertent intravascular administration (see section 4.9). 4. Appropriate steps should be taken to ensure that the patient thoroughly understands the indications and use of this device. The EpiPen® Auto-Injector should not be used for demonstration purposes. An EpiPen® Training Device is available to assist with patient education and practice. The healthcare professional, educator or caregiver should regularly review in detail with the patient, the package leaflet provided inside the EpiPen® Auto-Injector carton, which includes usage instructions for the EpiPen® Auto-Injector. 5. Patients should be instructed to dispose of the device safely after use by placing the used Auto-Injector in a sharps disposal unit. The EpiPen® Auto-Injector is intended for immediate self-administration. It is designed as emergency supportive therapy only and is not a replacement or substitute for subsequent medical or hospital care. 4.3 Contraindications Contraindications are relative as this product is intended for use in life-threatening emergencies. Adrenaline should not be used in patients with certain types of arrhythmia, cerebral arteriosclerosis and where vasopressor drugs are contraindicated e.g. thyrotoxicosis. Adrenaline is also contraindicated in shock (other than anaphylactic shock) in patients or during general anaesthesia with halogenated hydrocarbons or cyclopropane. Clinical conditions where special precautions are advised and interactions with other medicines are described in further detail in section 4.4. 4.4 Special warnings and precautions for use A severe anaphylactic reaction is a life-threatening emergency and administration of EpiPen® is not intended as a substitute for immediate medical care. In conjunction with the administration of adrenaline, the patient should seek immediate medical or hospital care. More than two sequential doses of adrenaline should only be administered under direct medical supervision. Page 2 of 11 The presence of anaphylactic shock should be confirmed before administering EpiPen®, as EpiPen® is only indicated for the treatment of anaphylaxis. Anaphylaxis may occur within minutes after exposure and consist of flushing, apprehension, syncope, tachycardia, thready or unobtainable pulse associated with a fall in blood pressure, convulsions, vomiting, diarrhoea and abdominal cramps, involuntary voiding, wheezing, dyspnoea due to laryngeal spasm, pruritus, rashes, urticaria or angioedema. For these reasons, auto-injectors should always be carried by such persons in situations of potential risk. EpiPen® Adrenaline Auto-Injector contains sodium metabisulfite, a sulfite, which may itself cause allergic-type reactions including anaphylactic symptoms and bronchospasm in certain susceptible persons, especially those with a history of asthma. The alternatives to using adrenaline in a life- threatening situation may not be satisfactory. The presence of a sulfite in this product should not deter administration for serious allergic reactions even if the patient is sulfite-sensitive. DO NOT INJECT INTRAVENOUSLY as cerebral haemorrhage may occur due to a sharp rise in blood pressure. Rapidly acting vasodilators can counteract the marked pressor effects of adrenaline if there is such inadvertent administration. Use with caution in patients with ventricular fibrillation, cerebral arteriosclerosis, prefibrillatory rhythm, tachycardia, myocardial infarction, phenothiazine-induced circulatory collapse and prostatic hypertrophy. Adrenaline should not be used in the presence of cardiac dilation. Adrenaline causes ECG changes including a decrease in T-wave amplitude in all leads of normal persons. Caution should be taken when administering in the presence of cardiac dilation. Adrenaline should be administered with caution in patients who have heart disease, including patients with cardiac arrhythmias, coronary artery or organic heart disease or hypertension. Adrenaline can cause potentially fatal ventricular arrhythmias including fibrillation, especially in patients with organic heart disease or those receiving other drugs that sensitise the heart to arrhythmias (see section 4.5). Anginal pain may be induced by adrenaline in patients with coronary insufficiency. Use with caution in patients with pre-existing conditions whereby the use of vasopressor drugs is contraindicated (e.g. thyrotoxicosis). Administer with caution to the elderly, and to individuals with diabetes, cardiovascular disease, hypertension, organic brain damage, narrow angle glaucoma, severe renal impairment, hypercalcaemia, hypokalaemia, hyperthyroidism and psychoneurosis. In patients with Parkinsonism the drug increases rigidity and tremor. Syncope has occurred following administration to asthmatic children. EpiPen® should not be injected into the hands, feet, ears, nose, buttocks or the genitalia as it may result in loss of blood flow to the affected area and may not provide effective treatment of anaphylaxis. Treatment should be directed at vasodilatation in addition to further treatment of anaphylaxis. If an accidental injection into one of these areas occurs, specialist medical advice must be sought immediately. Ensure the product is kept well clear of the face. Additionally, injection into the buttock has been associated with Clostridial infections (gas gangrene). Cleansing with alcohol does not kill bacterial spores, and therefore, does not lower this risk. Rare cases of serious skin and soft tissue infections, including necrotising fasciitis and myonecrosis caused by Clostridia (gas gangrene), have been reported at the injection site Page 3 of 11 following adrenaline injection for anaphylaxis. Clostridium spores can be present on the skin and introduced into the deep tissue with subcutaneous or intramuscular injection. While cleansing with alcohol may reduce presence of bacteria on the skin, alcohol cleansing does not kill Clostridium spores. To decrease the risk of Clostridium infection, do not inject EpiPen® into the buttock. Advise patients to seek medical care if they develop signs or symptoms of infection, such as persistent redness, warmth, swelling, or tenderness, at the adrenaline injection site. In patients with a thick sub-cutaneous fat layer, there is a risk for adrenaline not reaching the

  • An Intramuscular Injection Is an Injection Given Directly Into The
    Depo Lupron and Testosterone are both given by intramuscular injection. The following is a guideline on their administration. Eileen Durham, RN, NP Version 12 Jan 2010 Description Intramuscular (IM) injections are given directly into the central area of selected muscles. There are a number of sites that are suitable for IM injections; there are three sites that are most commonly used in this procedure described below. The volume of viscosity of the medication to be injected determines the site that should be used. IM injections cause stretching of the muscle fiber so the larger the muscle used the less discomfort. Intramuscular Injection Sites Depo Lupron Depo Lupron 3 month preparation should only be injected into the Gluteus medius due to the viscosity and volume of the medication approx. 1.5 – 2 cc. Depo Lupron 1 month preparation can be injection into the vastus lateralis or the gluteus medius. Testosterone Testosterone administered to adolescents and adults can be injected into any of the sites listed below, as long as the volume is 1 cc or less. For a volume of 1.5 use the vastus lateralis or Gluteus medius, if the volume is 2 cc you must you the largest muscle the Gluteus medius. If the volume is greater then 2 cc you must divide the dose and give 2 injections as the maximum volume in the Gluteal muscle is 2 cc. Testosterone administered to infants and toddlers use only the anteriolateral aspect of the thigh. Deltoid muscle The deltoid muscle located laterally on the upper arm can be used for intramuscular injections.

Drugs from four main classes of NPS were identified: psychostimulants, dissociative anaesthetics, hallucinogens (phenylalkylamine-based and lysergamide-based materials) and finally benzodiazepines. For inclusion in the review the 'user reviews' on drugs fora were selected based on whether or not the particular NPS of interest was used alone or in combination. NPS that were use alone were considered. Each of the classes contained drugs that are modelled on existing illegal materials and are now covered by the UK New Psychoactive Substances Bill in 2016.

  • Self-Administering a Vitamin B12 Injection
    Self-administering a Vitamin B12 injection This is usually given as an intramuscular injection, every 2-3 months. Alternatives to an intramuscular injection are: Oral Vitamin B12 at a dose of at least 1000mcg per day. • Available as tablets or a spray. They can be bought over the counter and available at most health food stores and pharmacies. • Oral Vitamin B12 is not recommended if: - If you have a bowel condition such as inflammatory bowel disease, Coeliac disease, small bowel overgrowth, bile acid malabsorption and short bowel (you will require injections) - You require an initial loading of B12 (soon after diagnosis) It is important to monitor your symptoms if you change to oral B12. If symptoms return, then the oral/sublingual dose can be increased to 2000mcg or you may need to consider starting back on injections. https://www.hollandandbarrett.com/shop/product/betteryou-pure-energy-b12-boost-oral-spray-60099160?skuid=099160 https://www.hollandandbarrett.com/search?query=%20Vitamin%20B12%20Tablets&utm_medium=cpc&utm_source=google&isSearch=true# gclid=EAIaIQobChMIh5nLgOH26AIVxLTtCh0JIA_GEAAYASAAEgJL-fD_BwE&gclsrc=aw.ds Subcutaneous (SC) injection; this is off-licence but still effective.

  • Can Hepatic Coma Be Caused by a Reduction of Brain Noradrenaline Or Dopamine?
    Gut: first published as 10.1136/gut.18.9.688 on 1 September 1977. Downloaded from Gut, 1977, 18, 688-691 Can hepatic coma be caused by a reduction of brain noradrenaline or dopamine? L. ZIEVE AND R. L. OLSEN From the Department ofMedicine, Minneapolis Veterans Hospital, University of Minnesota, Minneapolis, and Department of Chemistry, Hamline University, St. Paul, Minnesota, USA SUMMARY Intraventricular infusions of octopamine which raised brain octopamine concentrations more than 20 000-fold resulted in reductions in brain noradrenaline and dopamine by as much as 90% without affecting the alertness or activity of normal rats. As this reduction of brain catechol- amines is much greater than any reported in hepatic coma, we do not believe that values observed in experimental hepatic failure have aetiological significance for the encephalopathy that ensues.
